// php → node.js / nestjs

Modernize PHP backends with Node.js and NestJS.

Structured, typed service backends for APIs, integrations and asynchronous work — migrated module by module, while your current system keeps serving traffic.

// scope

Six kinds of backend work we take on.

:01 api

API modernization

Versioned REST or GraphQL contracts replacing endpoints scattered across PHP files.

:02 nest

NestJS architecture

Modules, providers and dependency injection for a codebase that scales with the team.

:03 int

Integrations

Payment, ERP, CRM and messaging integrations isolated behind clear adapters.

:04 evt

Event-driven systems

Domain events where they reduce coupling — not as a default for everything.

:05 job

Background processing

Cron scripts become observable queue workers with retries.

:06 ops

Enterprise backend concerns

Auth, audit logging, configuration and environments designed in, not bolted on.

// incremental

Route by route, not big-bang.

A routing layer sends each request to legacy PHP or the new service. Modules move one at a time, each verified before the next. Phase plans are set in the Proposal.

/webhooks/*legacy-php
/api/orderslegacy-php
/cron/reportslegacy-php
/api/billinglegacy-php
/admin/*legacy-php

Routing layer in front of legacy PHP. Nothing has moved yet; behavior is unchanged.

Three documents, in order.

No build starts from a sales call. Each step produces its own document and its own decision.

What does your PHP backend do at 2am?

Jobs, integrations, the endpoints nobody wants to touch — tell us about them. We’ll explain how an Assessment would be scoped.
